Comment 27 for bug 727064

So we have two solutions:

1) The solution proposed by Linus Torvalds, attachment #5264

Advantages: everything works the same as before
Disadvantages: a few extra cycles in certain memcpy's

2) The solution proposed by Ulrich Drepper, attachment #5323

Advantages: old binaries keep working
Disadvantages: newly compiled code remains affected

Clearly 1) is the most sensible solution as the only advantage of 2) is a few cycles, and has drastic disadvantages.
